Northeastern Bladderwort (Utricularia resupinata)

Life history

Species overview

Northeastern Bladderwort (Utricularia resupinata), a Wisconsin Special Concern plant, is found on wet, sandy shorelines of fluctuating soft-water ponds and lakes. Blooming occurs early July through early September; fruiting occurs throughout September. The optimal identification period for this species is late July through early September.

Habitats and landscapes

The Natural Heritage Inventory has developed scores indicating the degree to which each of Wisconsin's rare plant species is associated with a particular natural community or ecological landscape. This information is similar to that found in the Wildlife Action Plan for animals. As this is a work in progress, we welcome your suggestions and feedback.

General habitat information

Habitat description: Found on wet, sandy shorelines of fluctuating soft-water ponds and lakes.

Soils: Wet soils.

Natural communities

This table lists the natural communities that are associated with Northeastern Bladderwort. Scores for natural community associations are: "significant" association (score=3), "moderate association" (score=2) or the species can be present but is only weakly associated with the community (score=1).

Species guidance

The Endangered Resources Program has developed avoidance measures and management guidelines for plants on the Natural Heritage Working List. These are a work in progress, and we welcome your suggestions and feedback. Sources used in developing this information can be found here.

Avoidance measures

These are specific actions designed to avoid "take" (mortality) of this species.

Avoid known individual plant locations and conduct operations elsewhere when they are least likely to cause damage. Ideally, this would involve frozen, snow-covered ground. However, in areas of the state where frozen conditions are unreliable, very dry soils late in the growing season might be the best available alternative. Consult with a biologist, if needed.

Avoid broadcast spraying of herbicides; use care with spot spraying.

Management guidance

Management guidelines are additional considerations that may help maintain or enhance habitat for this species

Minimize disturbance to hydrology, including soil disturbance from rutting.

Avoid disturbance to shorelines and the forest-beach interface.

This species is likely sensitive to water quality. Following BMPs around streams and buffering associated drainages will reduce eutrophication and prevent water quality degradation.
